Low sleep quality in adolescents is an important public health concern, as it relates to both their current and future physical and mental health. Furthermore, subjective happiness is also often regarded as a major life goal. Although Japan is an economically powerful country, the reported levels of subjective happiness among Japanese adolescents is low. Thus, this study aims to examine the relationship between subjective happiness and sleep problems in Japanese adolescents.
We conducted a nationally representative cross-sectional study of adolescents enrolled in junior and senior high schools in Japan. We used a questionnaire to determine the prevalence of sleep problems (eg, insomnia, short sleep duration (SSD) and poor sleep quality) and to evaluate the participants' reported levels of subjective happiness. Multivariable logistic regression analyses were used to examine the associations between subjective happiness and sleep problems. Adjusted variables were basic demographic characteristics (eg, gender and school grade), lifestyle behaviors, and mental health status.
Data from 64,329 students were analyzed (age range 12-18 years, mean age 15.7 years, 53.9% male). The results indicated that reported levels of subjective happiness were strongly associated with the prevalence of sleep problems. Linear relationships can be observed between sleep problems and subjective happiness scores. The multivariable logistic regression analysis showed that dose-response association of subjective happiness score was observed with all three sleep problems.
Due to these findings, we recommend that policy makers and school officials educate adolescents on the importance of both subjective happiness and good sleep hygiene.
青少年睡眠质量差是一个重要的公共卫生问题，因为它与他们当前和未来的身心健康都有关。此外，主观幸福感通常也被视为主要的人生目标之一。尽管日本是一个经济强国，但报告显示日本青少年的主观幸福感水平较低。因此，本研究旨在探讨日本青少年主观幸福感与睡眠问题之间的关系。
我们对日本初中和高中的青少年进行了一项全国性的代表性横断面研究。我们使用问卷来确定睡眠问题（如失眠、睡眠持续时间短（SSD）和睡眠质量差）的流行率，并评估参与者报告的主观幸福感水平。多变量逻辑回归分析用于检查主观幸福感与睡眠问题之间的关联。调整变量包括基本人口统计学特征（如性别和学校年级）、生活方式行为和心理健康状况。
对 64329 名学生的数据进行了分析（年龄范围 12-18 岁，平均年龄 15.7 岁，53.9%为男性）。结果表明，报告的主观幸福感水平与睡眠问题的流行率密切相关。睡眠问题与主观幸福感评分之间存在线性关系。多变量逻辑回归分析显示，主观幸福感评分与所有三种睡眠问题均存在剂量反应关联。
鉴于这些发现，我们建议政策制定者和学校官员教育青少年主观幸福感和良好睡眠卫生的重要性。
